The S3 has twice the capacity of the S2 at 10,000mAh – 5,000mAh at 7.7V (38.5Wh) – that the company says is enough to nearly double an iPhone’s battery life, but that will vary depending on the model.The Kuxiu S3 is also Qi2.2-compatible so it can wirelessly charge compatible devices at up to 25W. Its larger battery means it’s over 100g heavier than the 145g S2, but Kuxiu has increased the number of N52 magnets it uses from 16 to 18 to help reduce the risk of the power bank being accidentally knocked off your phone. There’s an integrated kickstand now on the back, a small display showing its remaining capacity and charging status, and a built-in cable for charging other devices through a USB-C port with power delivery rated at up to 35W.The S3’s built-in USB-C cable can be completely removed if you want to use it to connect other devices. Image: KuxiuAs with the previous model, the S3 is more expensive than traditional wireless power banks offering similar capacity, charging rates, and features, but the cost of the technology should drop over time as manufacturing improves and increases. It’s available now for $149.98, but temporarily discounted to $68.99. If that seems hard to stomach, remember that while the capacity of most power banks will start to degrade after 300 to 500 cycles, the S3 should only see a drop to about 80 percent capacity after 1,000 charging cycles. It will have a much longer lifespan, and is less at risk from issues like fire and thermal runaway should you accidentally drop it.Follow topics and authors from this story to see more like this in your personalized homepage feed and to receive email updates.Andrew LiszewskiCloseAndrew LiszewskiSenior Reporter, NewsPosts from this author will be added to your daily email digest and your homepage feed.FollowFollowSee All by Andrew LiszewskiGadgetsCloseGadgetsPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All GadgetsNewsCloseNewsPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All NewsTechCloseTechPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All TechMost PopularMost PopularYou can play classic Nintendo games on these custom SNES-inspired Nike sneakersWyze’s new security camera watches your yard from inside your homeI’m officially done with YouTube KidsMicrosoft’s latest 13-inch Surface Laptop is down to $549.99, a new record low priceYou’re buying a Frame TV?

Kuxiu has released its third iteration of a solid-state power bank, the S3, building upon the foundation of its previous model. The S3 distinguishes itself through a significantly increased capacity of 10,000mAh – a doubling of the S2’s 5,000mAh – while also incorporating several new features and improvements. Key upgrades include support for Qi2.2 wireless charging at up to 25W, a built-in display that shows remaining capacity and charging status, a rear-mounted kickstand for hands-free use, and a removable USB-C charging cable for connecting other devices. The power bank features 18 N52 magnets to mitigate accidental drops, and utilizes a 35W USB-C PD output. The S3’s capacity is designed to nearly double the battery life of an iPhone, although this will vary by model. The increased capacity comes at a cost, as the S3 is notably heavier than its predecessor, approximately 100g more. Despite the higher price point – currently $149.98, temporarily discounted to $68.99 – Kuxiu claims that manufacturing costs should decrease over time. A noteworthy aspect of the S3 is its durability; the manufacturer anticipates a lifespan of around 80% capacity after 1,000 charging cycles, potentially outperforming traditional wireless power banks that often degrade more rapidly and are susceptible to issues like thermal runaway or fire hazards due to accidental damage.
